ST-CHP is a unique proposition that addresses the energy trilemma in South Africa by providing low cost distributed power generation, better control over security of supply and reducing emissions, whilst making power available in remote locations. It is a micro combined heat and power system generating 3.44 kW of power and delivering 25 kW of heat simultaneously. This system is capable of capturing and utilising renewable solar heat to reduce CO2 emissions, dependency on fossil fuels and operation cost, whilst benefitting from a multi-fuel combustion chamber (LNG, LPG, Diesel, Biogas) to cover over-night operation and the renewable intermittency and shortfalls, as well as making it adaptable in various locations. It will reduce the need for back-up diesel generators and consequently improve the air quality in South Africa because of reduced NOx emissions.
The aim of the project is to integrate Samad Power’s Micro Gas Turbine technology with solar parabolic dish and receiver with multiple facets (developed by the University of Pretoria) using an innovative evacuated membrane approach. A unique design for integrated thermal energy storage (TES) has been completed by the University of Birmingham in collaboration with the University of Pretoria. This will be equipped with a multi-fuel combustor developed by Cranfield University to increase market adoptability and eliminate the need for backup generators.
